xMPRo'vnMENT m PUMPS.

Schedule referred to in these Letters Patent and making part ol' thesame.

To all whom 'it may 'concern v Be itknown that I, CHARLES A. COWELL, ofNewark, in tlle'- county of Essex, and State ofNew Jersey,

Y have invented certain new and useful Improvements in Double-Acting;vand Anti-Freezing Pumps; and I do hereby declare'tliat the following isa full, clear,

.and exact description ofthe same, reference being had-a to theaccompanying drawings, and to the letters of reference marked thereon,making ,a part of these speciiications.

'a a represent a cylinder-rod.

Attached to the lower end of this rod is a valve, l),

which plays up and down in the 4upper end of the 1 H cylinder f.

This' rod'and valve yare so constructed as to allow another rod, e e, topass up and down in the same without interferngwith each other.

To this. inner rod is attached, at the lower end,-a

valve, d, which plays up and down in the' lowerend As the handle islowered, the rod a a passes down ward, plunging the valve b, while therod c c and valve d are lifted at the same time. The valves b and dacting in unison. as vone plunges, the other acts as a stop andlifting-valve, so that at every motion ofthe handle one valve is plungedand theother is lifted.

The cylinder f is located below/che platform, ano

fbetween this cylinder and the platform is a Small exhaust g, Where theremaining Water is allowed to pass out ofthe top of the pump, sol thatthe water may not be subjected to the action o f the weather, either hotor cold.

The connection is -formed ybetween the pump and water by means of a pipeattached to the lower end of the cylinder.v

This pump may he used with or without a local stop-valve in the bottomofthe cylinder at h.

Alihat I claim, isrlhe arrangement of the hollow shaft a and its valveb, interior working-rod e, and its valve d, with the i cylinder j, stockA, withexhaust g, and lever, with pitmen on each side of the fulerum e,for alternately operating the -rods a c, all substantially as herein setforth. A
